One of the libraries was called 'interlude', and it claims to be able to give line locations for errors in the Prelude. I was intending to upload them all as a group once I'd finished, but you might be able to make use of it here.

Although I had to change my source code a bit (changing calls to e.g.
`any' and `all' to have a Foldable prefix), this did work. My error
message now is:
dsat: Prelude.maximum: empty list
which tells me where my bug is. Thanks!
